Abstract

A drag-reducing undercarriage panel for a vehicle includes a planar main body sloping into an arcuate front section extending rearward over at least a portion of the planer main body creating a curved front edge; a pair of spaced outer members extending outward from opposite sides of a front portion of the planar main body; and multiple attachment sections for attaching the undercarriage panel to a vehicle. The undercarriage panel reduces or eliminates turbulent air beneath a moving vehicle caused by the vehicle's rotating front tires and uneven and rough undercarriage.

Description

FIELD OF THE INVENTION
The embodiments of the present invention relate to an undercarriage panel attachable to a vehicle chassis. The undercarriage panel serves to reduce drag and increase fuel efficiency of a vehicle.
BACKGROUND
Fuel efficiency is a significant factor with automotive vehicles. Better fuel efficiency is directly related to conservation of fossil fuels and reduction of carbon emissions. Drag is a primary factor impacting fuel efficiency. Turbulent air proximate to the vehicle in motion naturally increases drag thereby reducing fuel efficiency.
Accordingly, it would be advantageous to develop an undercarriage panel configured to eliminate or reduce the turbulent air created by air flow under a vehicle.
SUMMARY
In one embodiment, the undercarriage panel for a vehicle comprises a planar main body sloping into an arcuate front section extending rearward over at least a portion of said planer main body creating a curved front edge; a pair of spaced outer members extending outward from opposite sides of a front portion of said planar main body; and multiple attachment sections for attaching said undercarriage panel to a vehicle. When attached to a vehicle, the pair of spaced outer members are positioned forward of, and aligned with the tires of the vehicle.
In one embodiment, the undercarriage panel is fabricated of a rigid, yet flexible material, such that said undercarriage panel may absorb or flex when contacting debris or obstacles while the subject vehicle is in motion.
As detailed herein, the undercarriage panel reduces or eliminates turbulent air under the vehicle while in motion by preventing (or reducing the amount of) moving air from contacting the undercarriage of the vehicle and the rotating front tires. There are at least two benefits of reducing the turbulent air under the vehicle. First, drag is reduced, and second, uninterrupted ground effects maintain a downforce (higher pressure above vehicle than underneath vehicle) causing the vehicle to traverse the ground smoothly. Both reduced drag and uninterrupted ground effects increase the fuel efficiency of the subject vehicle.
Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.

 DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles in accordance with the embodiments of the present invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive feature illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.
The undercarriage panel described herein may be fabricated of any number of materials including, but not limited to, plastics, composites, alloys, metals, polymers, ceramics, glasses, woods and/or combinations thereof. The canopy may be fabricated using one or more techniques including, but not limited to, machining, additive printing, forming, injection molding, casting, thermoforming and/or combinations thereof. Those skilled in the art will recognize that other materials and fabrication techniques may be used. The undercarriage panel may be fabricated as a single piece or multiple pieces attached to one another. As used herein, an undercarriage of a vehicle is made up of any vehicle parts (e.g., motor, oil pan, axle, tires, radiator, etc.) which are at the bottom of a vehicle and interact with air moving under the vehicle.
FIG. 1A shows a standard pickup truck 100 and turbulence 110 created underneath the truck 100 while the truck is in motion. FIG. 1B shows the truck 100 and reduced/eliminated turbulence 130 resulting from the undercarriage panel 120 of the present invention being attached to the truck 100.
FIGS. 5A-5C show the undercarriage panel 120 according to the embodiments of the present invention. The undercarriage panel 120 broadly comprises a planar main body 150, a curved front edge 160, a pair of spaced outer members 170 and multiple attachment sections 180 for attaching said undercarriage panel 120 to a vehicle. The planar main body 150 slopes (FIG. 5B 157) into an arcuate front section 155 extending rearward over an upper surface of said planer main body 150 creating the curved front edge 160. The planar main body 150 shown in FIGS. 5A-5C comprises a generally uniform width along the length thereof.
In one embodiment, the curved front edge 160 is formed such that main planer body 150 may flex thereabout. Specifically, in one embodiment, the planar main body 150 is configured to flex about a horizontal center line 165 of the curved front edge 160. FIGS. 4A and 4B show the ability of the planar main body 150 to flex upward (see arrows A) about center line 165 of the front edged 160 when contacting debris or an obstacle 153.
As best seen in FIGS. 2, 3 and 6, when the undercarriage panel 120 is attached to a vehicle, the pair of spaced outer members 170 are positioned forward of, and aligned with, the front tires 175 of the vehicle. As shown in FIGS. 5A-5C, the spaced outer members 170 are positioned below or extend downward from the planar main body 150 to re-direct as much air as possible away from the front tires 175. Flaps 190 extending downward from said spaced outer members 170 further serve to re-direct air away from the front tires 175. Given moving air contacting fast-rotating front tires creates a significant amount of turbulent air, the outer members 170 and flaps 190 reduce the formation of a significant amount of turbulent air. As shown FIGS. 2 and 6, said planar main body 150 may taper 159 wider towards a rear thereof to cover additional vehicle undercarriage. As shown in FIG. 6, the long edges 163 of the planar main body 150 may also be raised to further channel air rearward without coming into contact with significant portions of the undercarriage of the vehicle.
In one embodiment, attaching said undercarriage panel 120 to a chassis of a vehicle is accomplished using attachment sections 180 and fasteners. As shown in FIGS. 5A-5C, three attachment sections 180 comprises flaps through which fasteners may be used to attach the front and mid-portion of the undercarriage panel 120 to the chassis of the vehicle. A rear edge 185 of the undercarriage panel 120 further includes pre-drilled holes 187 through which fasteners may be used to attach the rear portion of the undercarriage panel 120 to the chassis of the vehicle.
Although the invention has been described in detail with reference to several embodiments, additional variations and modifications exist within the scope and spirit of the invention as described and defined in the following claims.
